Below, the changing pattern (the 1st～the 3rd changing pattern) of the light source 21 utilizing light modulator 3 is described in detail.Here, will
Above-mentioned lure intensity, stopping intensity and killing intensity are set to p1, p2, p3.
Fig. 5 represents the 1st changing pattern, and Fig. 6 represents the step that brightness adjustment control based on the 1st changing pattern processes.Control electricity
The count value obtained by timer 31 is resetted (S11 of Fig. 6) by road 32, starts the timing (S12) made by timer 31.This
Time, the minimum activity p0 of ultraviolet is set to 0.1 μ W/cm by control circuit 322(S13), from being made by timer 31
The elapsed time (hereinafter referred to as timing time) that timing starts is the period (no in S14) within the 1st period t1, is tieed up
Hold.1st period t1 is substantially 15 minutes.If timing time have passed through and in the 1st period t1(S14 is), then control circuit 32 will
The activity of ultraviolet switches to stopping intensity p2(S15).It is the 1st period t1 and the total of the 2nd period t2 at timing time
Period within period, namely from be switched to stop the elapsed time after intensity p2 be the 2nd period t2 within period (S16
In no), control circuit 32 maintain stop intensity p2.2nd period t2 is substantially 15 minutes.If timing time have passed through above-mentioned conjunction
During meter (being in S16), then the activity of ultraviolet is switched to killing intensity p3(S17 by control circuit 32).Then, exist
Timing time be the 1st period t1, the 2nd period t2 and the 3rd period t3 total during within period, namely kill from being switched to
Hindering the elapsed time after intensity p3 is the period (no in S18) within the 3rd period t3, and control circuit 32 maintains and kills intensity
p3.If during timing time have passed through above-mentioned total (being in S18), then returning the process of S11.It it is substantially 30 points during 3rd
Clock.
Fig. 7 represents the 2nd changing pattern, and Fig. 8 represents the step that brightness adjustment control based on the 2nd changing pattern processes.This light modulation
Control processes in brightness adjustment control based on above-mentioned 1st changing pattern processes (seeing Fig. 6), and the process of S13 is altered to purple
The activity of outside line is set to lure the process (seeing Fig. 8) of the S21 of intensity p1.
Fig. 9 represents the 3rd changing pattern, and Figure 10 represents the step that brightness adjustment control based on the 3rd changing pattern processes.This light modulation
Control processes in brightness adjustment control based on above-mentioned 1st changing pattern processes (seeing Fig. 6), and the process of S13～S18 is altered to
The process (seeing Figure 10) of S31～S34.By above-mentioned change, omit the activity of ultraviolet is set to 0 the 1st during
T1, replaces, and extends the 3rd period t3 that the activity of ultraviolet is set to kill intensity p3, is changed to t3'45 and divides
Clock.
After the process of S12, the activity of ultraviolet is set to stop intensity p2(S31 by control circuit 32), in timing
Time is the period (no in S32) within the 2nd period t2, maintains and stops intensity p2.If timing time have passed through the 2nd period t2
(being in S32), then the activity of ultraviolet is switched to killing intensity p3(S33 by control circuit 32).At timing time it is
Period within during the total of the 2nd period t2 and the 3rd period t3', namely from be switched to kill after intensity p3 through out-of-date
Between be the period (no in S34) within the 3rd period t3', control circuit 32 maintains and kills intensity p3.3rd period t3' is substantially
45 minutes.If during timing time have passed through above-mentioned total (being in S34), then returning the process of S11.
Below, describe in detail and the 1st～the 3rd comparison pattern of above-mentioned 1st～the 3rd changing pattern contrast.Figure 11 represents the 1st
Comparison pattern.Under this comparison pattern, the activity of ultraviolet is always set to 0, does not radiate ultraviolet.Figure 12 represents the 2nd ratio
Relatively pattern.This comparison pattern is in above-mentioned 3rd changing pattern (seeing Fig. 9), strong being set to the activity of ultraviolet stop
The process of degree p2, is altered to be set to its activity the process of 0.Figure 13 represents the 3rd comparison pattern.Under this comparison pattern,
The activity of ultraviolet is always set to kill intensity p3, the ultraviolet of continuous radiation killed intensity p3.
Pest repelling according to the 1st changing pattern～the 3rd changing pattern and the 1st comparison pattern～the 3rd comparison pattern is imitated
The evaluation result of fruit, is shown in table 1 below.Further, as it has been described above, in each mode, 5 it are vaccinated with respectively when experiment starts
Tetranychid.
Table 1
As shown in Table 1 above, tetranychid reproductive capacity is very strong, if not irradiation ultraviolet radiation, then leaf as the 1st comparison pattern
Mite just bred to decades of times at 1.5 months.Because such reproductive capacity, even if so as the 1st changing pattern～the 3rd changing pattern
When formula, the 2nd comparison pattern and the 3rd comparison pattern radiate ultraviolet like that, the number of elements of tetranychid also increases than when inoculating.But,
Under 1st changing pattern～the 3rd changing pattern, comparing with the 2nd comparison pattern and the 3rd comparison pattern, the number of elements of tetranychid is suppressed to
Less than 1/4.Its reason is described below.
Under the 1st changing pattern～the 3rd changing pattern, the 2nd comparison pattern and the 3rd comparison pattern, the number of elements of tetranychid is with easy
Leaf rear side in irradiation ultraviolet radiation is compared, it is difficult to the face side of irradiation ultraviolet radiation becomes more, distinguishes that tetranychid is from leaf
The face side of the lateral leaf in the back side moves.Because the translational speed of tetranychid is the slowest, so for leaf as cucumber
For big plant, in order to shift from the lateral face side in the back side of leaf, need the time of more than 20 minutes.Therefore, only estimate
Leave such as more than 30 minutes more than needed, to kill intensity p3 irradiation ultraviolet radiation, it is possible to kill tetranychid.But, as the 3rd compares
Shown in the result of pattern, if distinguishing only Continuous irradiation ultraviolet, then can not get sufficient insecticidal effect.Deducing, it is former
Because tetranychid is frightened by the ultraviolet of strength, quickly flee from.On the other hand, although if making the ultraviolet under killing intensity p3 put
Image the 2nd comparison pattern is interrupted like that and carries out, then insecticidal effect somewhat increases, but its limitation.
On the other hand, under the 1st changing pattern～the 3rd changing pattern the most as above, the number of elements of tetranychid falls sharply.The
The common ground of 1 changing pattern～the 3rd changing pattern is particularly compared with the 2nd comparison pattern, is to kill intensity p3 radiation purple
Before outside line, radiate ultraviolet stopping intensity p2.It is to say, make tetranychid by stopping the ultra violet radiation under intensity p3
Action dull, in this condition radiate kill intensity p3 ultraviolet, can be under the situation not letting slip tetranychid with this
Tetranychid is sent in large quantities the ultraviolet killing intensity p3, it is possible to make insecticidal effect obtain tremendous raising.
In the present embodiment, particularly in the case of insect B1 is tetranychid, by the ultra violet radiation under low-intensity
Make the action dull of insect B1, afterwards by radiating ultraviolet with high intensity, it is possible under the situation not letting slip insect B1,
Ultraviolet to insect B1 Continuous irradiation high intensity, it is possible to kill insect B1.Thus, if insect B1 is adult, then can lead to
Crossing the Inhibit proliferaton of laying eggs preventing insect B1, laying eggs even if achieving, it is also possible to by the ultra violet radiation of high intensity, prevent
Only hatching, suppresses the generation of insect B1 with this, therefore, it is possible to the reliably anti-B1 that gets rid of insects.Furthermore, it is possible to by repeating ultraviolet
The change of activity, increase the reliability of effect of pest control.It addition, the activity of the ultraviolet sent by light source 21
Due to the most permissible simply by switching stage by stage among multiple setting intensity set in advance, thus activity is made to become
Structure needed for change is simple structure.
It addition, the 1st, in the case of the 2nd changing pattern, owing to comparing with the 3rd changing pattern, add utilization and lure intensity
During the radiation of the ultraviolet of p0, p1, thus generate the insect B1 fled from from ultraviolet and return to ultraviolet irradiation region
Possibility.In the case of that, these insect B1 can be sent ultraviolet to stop intensity p2 and killing intensity p3, thus,
The preventive effect of insect B1 is improved.Furthermore it is possible to stopped by the action of the time-out of ultra violet radiation, insect B1 and kill
Such a series of flow process, effectively further implements preventing and kill off of insect B1.
It addition, be set to more than 30 minutes during the radiation of the ultraviolet killed under intensity p3.Thus, it is tetranychid at insect B1
In the case of, even if tetranychid moves, such as, prepare to be prone to irradiate from the lateral ultraviolet in the back side that ultraviolet is difficult to be irradiated to
To face side flee from, it is also possible to its move period in make the ultraviolet of killing intensity p3 continue, to tetranychid prolonged exposure.Cause
This, it is possible to reliably kill tetranychid, driven away.
Below, the different example of above-mentioned embodiment it is described with reference to.In following different example, with above-mentioned embodiment phase

The variation pattern of the activity of 21A, 21B middle-ultraviolet lamp is the most roughly the same.It is to say, control circuit 32 make light source 21A,
The activity of 21B middle-ultraviolet lamp, with roughly the same timing, is changed to roughly the same value.
As above-mentioned embodiment, in the case of irradiating ultraviolet from a direction, it is not only leaf
Rear side, the leaf surfaces side being in when more leaves overlaps on light depth direction is also formed at shading, this shading sometimes
Place becomes the position of hiding of insect B1.It is directed to this, as long as owing to using this different example, not being easily formed at the most above-mentioned shading, because of
And the position of hiding of insect B1 can be reduced, the most effectively kill insect B1.Furthermore it is also possible to the leaf surfaces to plant P
Side and rear side both sides are substantially simultaneously with roughly the same intensity illumination ultraviolet, the particularly ultraviolet under killing intensity p3
During line radiation, can the most reliably eliminate the escape ground of insect B1, make the preventive effect of insect B1 be improved.
